This can be used as a robotics platform for beginners. When I was about to build the bot, honestly I had no idea what was I going to make. Initially I made a base like first picture. Oh well,my main ingredients were,

1. Hard cardboard

2. Hot glue

3. Strong papercraft glue

4. 3X Standard Servos

5. 4X mini servos

6. An Arduino board (You'll know why I am not mentioning the board name here)

7. Battery

8. 2X BO motors

9. 1X castor wheel

10. 3X Sonar sensors

11. wheels for BO motors

12. 3 Digit Voltage Readout module
